The complete V domain amino acid sequences of two myeloma inulin-binding proteins.
The myeloma proteins binding inulin afford a unique opportunity to study the V region patterns of variation because of the similarity in the VL as well as the VH regions. The diversity patterns in both the VL and VH regions suggest these proteins are encoded by multiple, very similar V gene segments or that somatic mutation may repeatedly generate identical variants. Because of the close similarity in the V domains of these proteins and the extensive idiotypic analyses that have been carried out previously, several interesting conclusions can be drawn about the nature of idiotypic determinants. First, a single amino acid residue may be involved in determining multiple idiotypic determinants. Second, hapten-inhibitable idiotypes may depend on residues within and outside the hypervariable regions. Third, idiotypic similarity does not always predict a corresponding sequence similarity.
